Fix conflicting function name * Mousekey change default to off * Fix to oled display adjust * make rev2 change pin assign change keymap * use master_buffer * Timing adjustment * Organizing files * Change Keymap * Change Keymap Add EISU and KANA Correct 4rows * NKRO default to disable * EXTRAKEY_ENABLE default to disable * add rgb reset key * rgb custom function enable * Extend font * add RGBLED_POWER default folder to helix/rev2 RGB_ENABLE to no * renamed directory * Disable RGBLIGHT_CUSTOM_DRIVER * Disable LOCKING_SUPPORT_ENABLE * Update bootloader setting * Change readme * Fixed argument error --- keyboards/helix/rev1/matrix.c | 316 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 316 insertions(+) create mode 100644 keyboards/helix/rev1/matrix.c (limited to 'keyboards/helix/rev1/matrix.c') diff --git a/keyboards/helix/rev1/matrix.c b/keyboards/helix/rev1/matrix.c new file mode 100644 index 0000000000..375057a6f7 --- /dev/null +++ b/keyboards/helix/rev1/matrix.c @@ -0,0 +1,316 @@ +/* +Copyright 2012 Jun Wako + +This program is free software: you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation, either version 2 of the License, or +(at your option) any later version. + +This program is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
